unzip

Extract contents of zip file

collapse all in page

Syntax

unzip(zipfilename)
unzip(zipfilename,outputfolder)
filenames = unzip(___)

Description

example

unzip(zipfilename) extracts the archived contents of zipfilename into the current folder, preserving the attributes and timestamps of each file. unzip can extract files from your local system or from an Internet URL.

If a file exists with the same name and the file is not read-only, MATLAB® overwrites it. Otherwise, MATLAB issues a warning. On Microsoft® Windows® platforms, the hidden, system, and archive attributes are not set.

example

unzip(zipfilename,outputfolder) extracts zipfilename into outputfolder. If outputfolder does not exist, MATLAB creates it.

example

filenames = unzip(___) returns a cell array of character vectors containing the names of the extracted files.

Open Live Script

Create a zip file and extract it to the folder archive.

Create the zip file examples.zip containing example MAT-files.

zip('examples.zip','*.mat',...
    fullfile(matlabroot,'toolbox','matlab','demos'))

Extract examples.zip to the folder archive.

exampleFiles = unzip('examples.zip','archive')
exampleFiles = 1×40 cell array
    {'archive\accidents.mat'}    {'archive\airfoil.mat'}    {'archive\airlineResults.mat'}    {'archive\cape.mat'}    {'archive\census.mat'}    {'archive\clown.mat'}    {'archive\detail.mat'}    {'archive\dmbanner.mat'}    {'archive\durer.mat'}    {'archive\earth.mat'}    {'archive\fatalities.mat'}    {'archive\fluidtemp.mat'}    {'archive\flujet.mat'}    {'archive\gatlin.mat'}    {'archive\gatlin2.mat'}    {'archive\integersignal.mat'}    {'archive\logo.mat'}    {'archive\mandrill.mat'}    {'archive\mapredout.mat'}    {'archive\membrane.mat'}    {'archive\mri.mat'}    {'archive\patients.mat'}    {'archive\penny.mat'}    {'archive\quake.mat'}    {'archive\seamount.mat'}    {'archive\spine.mat'}    {'archive\stocks.mat'}    {'archive\tetmesh.mat'}    {'archive\topo.mat'}    {'archive\topography.mat'}    {'archive\trimesh2d.mat'}    {'archive\trimesh3d.mat'}    {'archive\truss.mat'}    {'archive\usapolygon.mat'}    {'archive\usastates.mat'}    {'archive\usborder.mat'}    {'archive\vibesdat.mat'}    {'archive\west0479.mat'}    {'archive\wind.mat'}    {'archive\xpmndrll.mat'}



                
Download and extract a zip file from a URL to a local
                    folder.

            
Suppose you have the zip file example.zip stored at the
                        URL http://example.com/example.zip. Download and extract
                        the file to the example folder.
url = 'http://example.com/example.zip';
unzip(url);
Input Arguments
collapse all

                    
Name of zip file to extract from, specified as a character vector or a
                        string scalar. If zipfilename has no extension,
                            MATLAB searches for zipfilename appended with
                            .zip.

                    
zipfilename must include a path relative to the current
                        folder or an absolute path.

                    
If zipfilename is a URL, zipfilename
                        must include the protocol type (for example, http://).
                            MATLAB downloads the URL to the temporary folder on your system, and
                        then it deletes the URL on cleanup.

                    
unzip does not support password-protected or
                        encrypted zip archives.

                
Data Types: char | string

                    
Target folder for the extracted files, specified as a character vector or
                        a string scalar.

                
Data Types: char | string
Tips
  • To extract a zip file that contains non-7-bit ASCII characters, extract the
                    file on a machine that has the appropriate language/encoding settings.
